Terre Haute _has_ to mean, first of all, a small city in the midwest for
any u.s. writer. There is a huge u.s. literature which alludes to or
even bases itself on the life of such cities. A famous u.s. political
slogan is, "But will it play in Peoria," and Pound brings in Peoria at
the climax of one of the early cantos. Probably had it been the
temptation of the pun offered by Terre Haute, Eliot would have used
Peoria for the poem.
